JAMES C. GILBERT, OF LEEDS JUNCTION, MAINE.

YOKE-RING ATTACHMENT FOR THE POLES OF OX-CARTS.

Specification of Letters Patent No. 23,673, dated April 19, 1859;

To all whom it may concern:

Be it known that I, JAMES C. GILBERT,

vof Leeds Junction, in the county of Androscoggin and State of Maine,have invented an Improved Yoke-Ring Attachment for the Poles ofOx-Carts; and I do hereby declare that the same is fully described andrepresented in the following specification and the accompanyingdrawings, or' which- Figure l, is a side elevation of the tongue or poleof an ox-cart having my invention applied to it; Fig. 2, an undersideview of the same; Fig. 3, a longitudinal section of it, and Fig. 4c, atransverse section taken through its spring slider.

The object of my invent-ion is to enable a, person readily to attach to,or detach from, an ox-cart pole the ring of a. yoke; the nature of thesaid invention consisting in the peculiar arrangement of a backingbearer and an engaging notch ot' a spring slider' with respect to and soto operate as hereinafter explained with a draft hook anplied to theunderside of such pole or tongue.

In the l'igures, A, exhibits the pole, and B, the yoke ring; C, is ametallic hook fastened to the underside of the pole and formed in mannersubstantially as shown in such drawings. .I ust in rear of the said hookis a spring slider D, which is applied to the tail part a, of the hookand against a spring Z), (arranged as shown in Figs. 3, and 4,) so as tobe capable of sliding up and down in the pole and part d, the saidslider being formed with one or more project-ions o, o, to prevent itfrom falling out of place within its socket of the said tail part. The

slider has a curved notch e, constructed in it as shown in the drawings,the same being arranged immediately below and in rear of the front partf, of the slider. Such part f, may be termed the backing bearer, as itis against such part that the ring is borne l during the process ofbacking the cart. This backingl bearer when the ring is within therecess of the hook should extend into the said recess so far that thedistance or' its lower end from the point of the hook, shall be lessthan the thickness or' the ring, the same being in order that it maycoperate with the hook in maintaining the ring with` in the cavity orrecess of the hook. Furthermore, the backing bearer or the slider ofwhich it forms a part should be capable of being moved upward far enoughto enable the ring to be detached from the hook.

In the process of attaching the ring to the pole the latter is to beextended into ituntil the lower part of the ring may come into theengaging notch e, when by pressing the pole downward on the ring, or bydrawing the ring upward, the engaging notch will be made to cooperatewith the point of the hook so as not only to cause the slider to riseupward, but force the ring into the recess of the hook, which havingtaken place, the slider will be immediately driven downward by itsspring so as to move the backing bearing f, into a position for holdingthe ring in place and serving as a shoulder ior it to bear against whilethe cart is being backed by the animals which may be yoked to the ring.

Having thus described my invention, what I claim is- The above describedarrangement of the backing bearer j", and the engaging notch c, of thespring slider D, with respect to, and to operate with, the draft hook C,substantially in manner as hereinbefore specilied.
